LINOTYPE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 722,353, dated March10, 1903.

Application filed January 8, 1908. Serial No. 138,264. (No model.)

ing one at a time from the magazine in front of a star-wheel are forcedhorizontally thereby into a channeled assembler, the star-wheel pushingthe line forward so that the incoming matrices may enter at the end ofthe same. There are used in this machine certain elongated expansiblespacers, consisting of two oppositely-tapered wedges. These spacers aredropped into the line from above through essentially the same path asthe matrices. The matrices approach the line with considerable velocityand are liable to become battered or mutilated by their impact againstthe bottom of the assembler.

The aim of my invention is to provide a yielding device or buffer whichwill serve to check the momentum of the matrices before they strike theassembler and which will at the same time permit the space-bands to enter without interference.

To this end it consistsin a yielding buffer located between thestar-wheel and the assembler and having its upper end of peculiar form,as hereinafter described, whereby it is adapted to check the matrices,but permit speedy passage of the spacers.

Figure 1 is a perspective view representing my device applied to theassembling devices of a Mergenthaler machine. Fig. 2 is a perspectiveview of the buffer detached. Figs. 3 and i are diagrams illustrating themanner in which the buffer acts on a space-band and a matrix,respectively.

Referring to the drawings, A represents an inclined belt or apron overwhich the matrices descend to inclined guiding-surfaces B, which directthem downward in front of a vertical star-shaped wheel 0, by which theyare crowded forward horizontally into the end of the assembler.

E represents my buffer or resistant, consisting of a spring e,underlying the frame and fastened thereto at the rear end by a spring 6or its equivalent, and of a block or resistant e fixed to the forwardend of the spring, with its upper end standing below and in front of thestar-wheel in the path of the incoming matrices and spacers.

The matrices, which are short and have flat lower ends, as usual, willstrike upon the buffer, and being checked or retarded thereby areinstantly pushed forward therefrom into the assembler. The spacers H(shown in Fig. 4) being of much greater length than the matrices andfalling but a short distance at a lower velocity must not be retarded. Itherefore cut away the sides of the resistant or bufier on inclinedlines, as shown in the drawings, so that it presents a flat uppersurface only at the middle. This remaining surface is sufficientlynarrow to pass through the vertical notch in the lower ends of thespacebands. It follows, therefore, that when a space-band descends itslower end will straddle the center portion of the resistant and strikeon the inclined surfaces at the sides, the result of which is to carrythe end on the band instantly forward clear of the resistant,

so that the end of the band may continue its motion downward through theassembler without appreciable loss of time. The important feature ofconstruction in this regard lies in so forming the buffer that it willarrest or check the matrices, which move with great velocity, but willnot appreciably check the space-bands, which move at slower speed.

The operative end of the buffer may be made of any suitable material,and it maybe supported by a flat spring, as shown, or in any otherappropriate manner.

Having described my invention, what I claim is 1. In the assemblingmechanism of a linotype-machine, a bufier having a surface to check themotion of the incoming matrices and an inclined surface to deflect thespacers and prevent their retardation.

2. In a linotype-machine, an assembler arranged for delivering matricesand spacebands individually thereto, an intermediate yielding bufferhaving a surface at substantially right angles to the path of thematrices, to retard their advance, and an inclined surface to deflectthe spacers and prevent their retardation.

3. lhe attachment for a linotype-machine, consisting of aretarding-piece provided with a surface to receive the impact of thematrices and an inclined surface to deflect the spacers.

4. In a linotype-machine and in combination with the fiat-ended matricesand the 10 spacers having notched ends, the bulfer or retarding devicehaving surfaces in diiferent positions to receive the impact of thematrices and the spacers respectively.

In testimony whereof I hereunto set my hand, this 2d day of January,1903, in the 15 presence of two attesting Witnesses.
